First CAN FD Class 3 Compatible Common Mode Choke Coil

Murata has announced the wire-wound common mode choke coil (CMCC) DLW32SH101XF2, which is claimed to be the world's first CMCC to support the most challenging requirements of differential to common mode rejection (DCMR) Class 3.

As a result, the new device fulfills the IEC62228-3 requirement for use in CAN FD, the flexible data rate version of CAN bus that is necessary for next-generation automotive networks.

Technologies that control automobile performance are advancing rapidly with the aim of providing greater efficiency as well as safer and more comfortable driving. In keeping with the demand for greater efficiency, safer and more comfortable driving and the higher levels of data involved, faster automotive networks are required for connecting ECUs, sensors, and motors, with the result that conventional CAN, which transmits data at a rate of up to 1Mbps, is being replaced with the faster CAN FD.

The DLW32SH101XF2 offers a common-mode inductance of 100uH and is rated for currents up to 115mA and voltages of 50Vdc. The surface mounted device is constructed in 1210 package, measuring just 3.2mm x 2.5mm making it the world's smallest CAN FD CMCC supporting Class 3 due to Murata's unique wire-wound structure.

The RoHS and REACH compliant device is capable of operating in temperatures between -40 degrees C and +125 degrees C. It is qualified to AEC-Q200, confirming its suitability for demanding automotive environments.
